Dewey

SAGA's next-generation machine that defined the "eternal second best."

Dewey was Dreamcost's last consumer doll released by SAGA Corporation, and it has already been 8 years since its production ended.
Kaori bought it several years ago when it was being sold at a clearance sale.
It is equipped with an AI that is set up to be a "clueless character," with few words, no clear emotions, and always seems to be in a state of confusion.
The most distinctive feature of this character is the unit attached to its back.
Inside this unit is a bellows-type arm, which can be freely manipulated in conjunction with Dewey's AI.
This unit is an original part that Kaori, its master, made herself.
The name "Dewey" was given by Kaori after the violent driving sound it makes when reading the ROM.
By the way, she has two more units of the same type.
